Off the line, the Bmw 125i hits 100 km/h in 6.15 s versus 6.56 s for the Cooper S FWD. At this point, the Bmw 125i leads by 0.41 s and sits roughly 9 m ahead.
At 200 metres, the Bmw 125i is doing 131 km/h against 132 km/h for the Cooper S FWD. The gap is 0.31 s. The gap remains stable from the start.
At 400 metres standing start, the Bmw 125i crosses the line in 14.35 s versus 14.62 s. The 0.27 s gap represents roughly 12 m of track - two to three car lengths.
Past 400 metres, the gap narrows. The Bmw 125i maxes out at 243 km/h while the Cooper S FWD keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.22 s.
At 1,000 metres, the Bmw 125i finishes in 25.91 s versus 26.02 s, with just 0.12 s to spare. The Cooper S FWD fails to fully close the launch gap.
Electronically capped at 243 km/h, the Bmw 125i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (6.25 kg/hp vs 5.86 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.51 seconds. The 0.41 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
